.A spring S ds rattach'edat tone eud ito .the

depending lug c 'convenient'lyrbyhooking5the ICC arranged as to be relaxed on the forward beat of the lay and put under tension on the backward beat. If the detent-pawl ha is disengaged from the link h the thread-parter will be moved into the position shown in Fig. 3 on the next backward stroke of the lay, as will be obvious, the tension of the spring S when subjected to the pull of the lay being greater than that of the actuating-spring 8 When the lay beats up and relaxes the spring S then the actuating-spring will be free to act to retract the thread-parter and to return it to normal position.

When the loom is running properly, the head of the arm will be maintained in the position shown in Fig. 1, with the link-support 9 in the position shown in Fig. 2 to hold the link up, so that the pawl 72. can engage the shoulder 71 as described, and the periodical pulling action of the spring S will have no efiect on the thread-parter. If, however, the filling fails, it will be detected by one or the other of the detectors, depending upon the pick on which it fails, or it may be detected by both. If the detection is first made by the detectorf on the pick from right to left, then on the return pick a change of filling will be effected when the shuttle is in the box B and as the shuttle is about to enter that box on the shot from left to right the detector 9 will detect the absence of filling, and the slide g will be moved outward in well-known manner, swinging the arm g withit and withdrawing the support g from beneath the link It so that the'latter will drop onto the breast-beam, and thus disengage the link from its pawl 71, the stop 77. then acting to prevent the pawl from following down. This occurs while the lay is forward and the filling is being replenished, and then the lay begins to move back. Inasmuch as the threadparter has been released the pull on the spring S will move it into operative position, (shown in Fig. 3,) and while the lay is going back the shuttle is thrown from right to left, so that the filling is laid in the shed and the filling end will extend from the replenishing mechanism to the nearer edge of the cloth. The lay heats up with the shuttle in the left-hand shuttle-box, and the filling just laid is beaten in at the fell; but the forward movement of the lay slackens the'tension of the spring S sufficiently to permit the actuating-spring s to operate, retracting the thread-parter; but it does not then engage and part the filling end, as the latteris not brought into the field of action of the parter until the filling has been beaten in. The beating-in is efiected as the lay completes its first forward stroke following replenishing,and the lay then moves back, and on such backward movement the shuttle is thrown from the left-hand box to the one at the right-hand side of the loom; but on its backward stroke the lay again stretches the spring S and moves the threadparter again into operative position, and this time the hooked end of the parter extends over the filling end 25 as in Fig. 3, ready to engage it. It must be remembered that the weft-hammers move once for every two beats of the lay, operating alternately, andthus the weft-hammer W will not have released the detector gfrom its control until after the second pull by the lay on the spring S so that when such pull occurs the threadparter is still free to be moved into operative position the second time. Now the shuttle having been shot from left to right, the lay beats up the second time after replenishing, and as it'moves forward it relaxes the tension of the spring S and the actuatingspring 5 operates the thread-parter, retracting it and severing the filling end i by the shearing action ofthe lower edge of the parter as it is drawn across the upright edge of the blade a, the severing being effected before the detector q can detect the presence or absence of the running filling. As the parteris retracted the spring 5 returns the link h to its normal position, riding up over the support g which in the meantime has returned to the position shown in Fig. 2, and the pawl 72. will engage the shoulder 72 whereby the thread-parter will be maintained in its inoperative position, so that the detector at the replenishing side of the loom can properly perform its function of feeling for the running filling on every alternate forward beat of the lay. Should the filling fail on the shot from left to right and be first detected by the detector g, the thread-parter will be operated as described, and on the next beat-up of the lay the detectorf will detect absence of filling and the parter will be projected as the lay goes back and retracted as it beats up with the shuttle in box 13*, this second operation of the parter accomplishing nothing, but the detector Q will again detect absence of filling on such beatup, and from this point the operation of the parts is precisely as has been described when the detectorf is the first to detect filling failure. Jonsequently there will be four operations of the thread-parter when failure is detected first by detector g, with severance of the filling end by the fourth operation, as opposed to two operations of the parter and severance of the filling end by the IIO second operation, when failure is first detected by delectorf. WVh'en the temple is moved outward by the beat-up of the lay in usual manner, the arm h will slide over the support g and return to the position shown in Fig. 2 when the temple moves inward as the lay goes back, the support g still maintaining the pawl 71 in holding engagement with positioned thread-parter, to first sever the &

end of the knock-0E lever 12 is shown in the path of and to be engaged by the dog 61 substantially in the manner shown and described in United States Patent No. 529,943, dated November 27 1894.
